Wartime intrigue spans the lives of three women—past and present—in this emotional novel from the acclaimed author of The Last Year of the War. February, 1946. World War Two is over, but the recovery from the most intimate of its horrors has only just begun for Annaliese Lange, a German ballerina desperate to escape her past, and Simone Deveraux, the wronged daughter of a French Résistance spy. Now the two women are joining hundreds of other European war brides aboard the renowned RMS Queen Mary to cross the Atlantic and be reunited with their American husbands. Their new lives in the United States brightly beckon until their tightly-held secrets are laid bare in their shared stateroom. When the voyage ends at New York Harbor, only one of them will disembark... Present day. Facing a crossroads in her own life, Brette Caslake visits the famously haunted Queen Mary at the request of an old friend. What she finds will set her on a course to solve a seventy-year-old tragedy that will draw her into the heartaches and triumphs of the courageous war brides—and will ultimately lead her to reconsider what she has to sacrifice to achieve her own deepest longings.

Peter Orner zeroes in on the strange ways our memories define us: A woman's husband dies before their divorce is finalized; a man runs for governor of Illinois and loses much more than an election; two brothers play beneath the infamous bridge at Chappaquiddick. Employing the masterful compression for which he has been widely praised, Orner presents a kaleidoscope of individual lives viewed in startling, intimate close-up. Whether writing of Geraldo Rivera's attempt to reveal the contents of Al Capone's vault or of a father and daughter trying to outrun a hurricane, Orner illuminates universal themes. In stories that span considerable geographic ground -- from Chicago to Wyoming, from Massachusetts to the Czech Republic -- he writes of the past we can't seem to shake, the losses we can't make up for, and the power of our stories to help us reclaim what we thought was gone forever. "A ravishing collection, full of wisdom, grief, beauty, and especially surprise." -- Anthony Doerr, author of The Shell Collectors

Nelson Mandela is dead and his dream of a rainbow nation in South Africa is fading. Twenty years after the fall of apartheid the white Afrikaner minority fears cultural extinction. How far are they prepared to go to survive as a people? Kajsa Norman's book traces the war for control of South Africa, its people, and its history, over a series of December 16ths, from the Battle of Blood River in 1838 to its commemoration in 2011. Weaving between the past and the present, the book highlights how years of fear, nationalism, and social engineering have left the modern Afrikaner struggling for identity and relevance. Norman spends time with residents of the breakaway republic of Orania, where a thousand Afrikaners are working to construct a white-African utopia. Citing their desire to preserve their language and traditions, they have sequestered themselves in an isolated part of the arid Karoo region. Here, they can still dictate the rules and create a homeland with its own flag, currency and ideology. For a Europe that faces growing nationalism, their story is more relevant than ever. How do people react when they believe their cultural identity is under threat? Bridge Over Blood River's haunting and subversive evocation of South Africa's racial politics provides some unsettling answers.

From the author of the “full-throttle thriller” (A. J. Finn) No Exit—a riveting new psychological page-turner featuring a fierce and unforgettable heroine. Three months ago, Lena Nguyen’s estranged twin sister, Cambry, drove to a remote bridge seventy miles outside of Missoula, Montana, and jumped two hundred feet to her death. At least, that is the official police version. But Lena isn’t buying it. Now she’s come to that very bridge, driving her dead twin’s car and armed with a cassette recorder, determined to find out what really happened by interviewing the highway patrolman who allegedly discovered her sister’s body. Corporal Raymond Raycevic has agreed to meet Lena at the scene. He is sympathetic, forthright, and professional. But his story still seems a bit off. For one thing, he stopped Cambry for speeding just an hour before she supposedly leaped to her death. Then there are the sixteen attempted 911 calls from her cell phone, made in what was unfortunately a dead zone. But perhaps most troubling of all, the state trooper is referred to by name in Cambry’s final enigmatic text to her sister: Please Forgive Me. Lena will do anything to uncover the truth. But as her twin’s final hours come into focus, Lena’s search turns into a harrowing tooth-and-nail fight for her own survival—one that will test everything she thought she knew about her sister and herself...
